592 Use gfc_is_data_pointer to test for pointer attribute.
593 * dependency.c (gfc_is_data_pointer):
594 Support pointer-returning functions.
596 2009-01-03 Daniel Franke <franke.daniel@gmail.com>

600 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
603 * resolve.c (resolve_call): When searching for proper host
604 association, use symtree rather than symbol. For everything
605 except generic subroutines, substitute the symtree in the call
606 rather than the symbol.
